UNETED STATES ARTHUR R. SELDEN, OF ROCHESTER, NEW YORK.

LOOSE-LEAF BINDER.

Application filed October 31, 1921. Serial No. 511,864.

To all whom it may concern:

Be it known that I, ARTHUR R. SELnnN, a citizen of the United States,and resident of Rochester, in the county of Monroe and State of NewYork, have invented certain new and useful Improvements in Loose- LeafBinders, of which the following is a specification.

The present invention relates to loose leaf binders and moreparticularly to the type employing impaling projections passing throughthe sheets or leaves to be held. An object of this invention is toprovide an impaling projection which may readily be made of differentlengths. Another object of this invention is to provide an impalingprojection formed of two section connected by screw threads, one ofwhich is rigidly connected to a binding member and the other of whichturns on the rigidly secured one. Still another object of the inventionis to provide an adjustable impaling projection which will maintain itseffective condition of uniform diameter, so that for any extension itsdiameter throughout will correspond with the openingsinthe leaves. Afurther object of the invention is to so house the operative parts thatthey will not be visible, while yet maintaining a compact structure.

To these and other ends the invention consists of certain parts andcombinations of parts, all of which will be hereinafter described, thenovel features being pointed out in the appended claims.

In the drawings:

Fig. 1 is a plan view of the rear end of the binder with one half shownin sectio on the line 11, Fig. 2;.

Fig. 2 shows in elevation the rear end of the binder with one'half shownin. section on the line 22, Fig. 1;

Fig. 3 is a sectional view through the ear edge of the binder on theline 3-3,

Fig.1 is a sectional view of one of the impaling pins in the directionof its length;

Fig. 5 is a detail view showing the mannor in which the impaling pinsare adjustable; and

Fig. 6 shows one of the impaling pins in elevation. I

In the illustrated embodiment of the invention the binder comprises twomembers each formed of a cover 1 connected by a flexible or hingingportion 2 with a binding member. Each binding member, in this instance,embodies a flat tube or hollow member 3 and two impaling pins or posts,the

impaling posts preferably being supported from tubular inserts 3,fitting in the tube 3. v In this instance, each impaling projection iscomposed of an end member 1 having a screw-threaded projection 5, one ormore intermediate members 6, each having a screw-threaded soc-ket- 7 forreceiving the screw-threaded projection 5 and having a Screw-threadedprojection 8 for interlocking with another section. In addition to oneor more intermediate sections 6, the post may embody a section 9 which,in this instance, is of tubular formation and has threaded portions 10and 11 respectively, one for engaging a threaded projection on anothersection and the other for engaging a threaded section 12 which projectsfrom an inner wall of the hollow member 3 through an opening 13 in theopposite wall. It is apparent that with this invention the impaling pinsor posts may be made of different lengths by adding or eliminatingsections 6, and it is also apparent that the length may be varied byadjusting the section 9 on the threaded section or projection 12.

With the end in view of holding the section 9 in difl'ere'nt adjustedpositions on the screw threaded section 12, the section 9 may beprovided with a longitudinally eX- tending groove or slot 1 1 and alocking device may be provided preferably within the tube 3. In thisinstance, this locking device is in the form of a lever 15 pivoted at 16to the insert 3 and having a nose 17 adapted to enter the slot 141, asshown in Figs. 1, 4 and 5. A spring 18 acts on this lever normally tohold the latter toward locking position. One end of the lever extendsinto slots 19 formed in the tube 3 and insert 3 so that such lever maybe pressed out of locking position against the action of its spring 18.A series of indications or marks 20 may be provided on the member 9 toindicate the adjustment of the impaling pin or post.

The posts on one of the binding members are situated nearer togetherthan those on the otherbinding member, and these two posts operatethrough openings 21 in the leaves 22. The posts which are farther re-110 moved operate through openings 23 in the leaves. This arrangementpermits both of the binding members to support the leaves in properrelation for cooperation with theimpaling posts or projections of theother member.

For the purpose of loclzi'ng the binding members together means isprovided on oneof the binding members for cooperation with the impalingposts or projections of the other binding member. In this instance, twolocking devices are provided on the-binding I member that icarries theposts passing through the openings 21 of the leaves. These lockingdevices, in this mstance, each embody a lever 24 mounted'to turn on apin 25, which i's'supported by two ears 26 struck up from theinsert-tube 3. one end 27 formed with an openingadapted to receive oneof the ianpaling pins or posts, in order that the walls of the openingsmay clutch or grip the postto prevent the'latter being withdrawn fromthe binding member carrying the locking device. A spring 28 acts on thisclutch lever to 'hold' it inclutclr ing position. The clutch lever alsohas an end- 29 disposed adjacent alined openings 30 in the-tubes 3 and 3so that pressure may be received from 'a finger passed through suchopenings.

simultaneously and thispermits the two b1nd1ng members to be separated.The cloth 31, whichcovers thebinding members except at their ends whichare-closed by caps 31 also covers the openings 19 and 30,

so that while the levers 15 and 25 may be operated from the exterior ofthe binding members, the operating ends ot'suclr levers are invisible.

The impahng' posts or pro ections are made of lengths to correspond tothe number of leaves held between'the binding members, this result beingsecured by eliminat- .ing the sections 6 of the post orby-adding as"many of such 'sectionsas desired and, at the 1 same time, ad usting thesections 9 on the screw section 12. Owing to'th-e fact that thescrew-thremfled inner sections of the impaliug' posts pro ect from theinner walls of the hollow binding members through openings in oppositewalls, the posts for any adjustment throughout their effective lengthsand corremaintain a unittorm diameter spond with the diameter of theopenings in the leaves. The twobmdmgmembers are This lever has Inorderto release the binder, both of the clutch levers must be operatedfitted together and the locking clutches automatically slide over theposts or projections which pass through the openings 23 in.

the leaves, and establish a clutching relation with said posts orprojections and prevent the separation of the binding member until thefinger portions 29 of the clutching members are depressed when the postsare freed and the binding members may be separated.

What I claim as my invention and desire to secureby Letters Patent is:

-1. A-loose leaf binder embodying an impaling post or projectioncomprising two provided with a longitudinally extending notch, and alocking device cooperating with the walls of the notch to hold thesection againstturning, a spring acting on said locking device tomaintain 1t normally toward locking position.

3. Aloose leaf binder comprising a tubular bindingme'mber having anopening in one wall, an impaling pin or projection embodying twosectionsone of which is in the 'form of a screw-threaded projectionextending-from an inner wall of the tubular binding-member through theopening and the other of which turns in said opening on saidscrew-threaded "projection, a locking device for said second-mentionedsectlon arranged within said tubular binding member and. having aportion operable from the exterior of said binding member.

4. A loose leaf binder comprising a hollow binding member provided withan opening in one wall, an externally threaded post section secured toan inner wall of said binding member, and extending through "aidopening, and an internally threaded post section adjustable in saidopening on the firstnamed post section.
